RESUMEN

Multiple approaches are used to treat acne scars, but some are expensive, ineffective, and cause complications. We aimed to evaluate the efficacy and safety of ultra-pulsed CO2 fractional laser combined with 30% supramolecular salicylic acid in the treatment of acne scars in a prospective split-face control study. Twenty patients with facial symmetrical acne scars were enrolled. One side of face was randomly treated with 30% supramolecular salicylic acid, and two sides were treated with ultra-pulsed CO2 fractional laser. The Echelle d'evaluation clinique des cicatrices d'acne (ECCA) scale was used to evaluate the clinical efficacy before and 3 months after treatment, and a quartile scale was used to self-evaluate the improvement of patients. A visual analog scale was used to record pain scores after each treatment, and side effects and other adverse reactions on the face were recorded. All the patients completed treatment and follow-up. There was statistical difference in ECCA scores of bilateral facial acne scars after three treatments (p < 0.001). ECCA scores on the combined side were lower after three treatments than those on the laser side (p = 0.003). The patient satisfaction quartile scale on the combined side was higher than that on the laser side alone (p = 0.015). Ultra-pulsed CO2 fractional laser combined with 30% supramolecular salicylic acid has better efficacy in the treatment of acne scars than laser alone, and patient self-assessment of combined treatment has a greater degree of improvement in acne scars, and does not increase patient pain scores and related adverse reactions.
